In this follow-up study a light-cured glass ionomer lining cement was evaluated as a cavity-sealing material in calcium hydroxide pulpotomies in primary molars after one and two years. The pulpotomy dressing was a suspension of pure calcium hydroxide with either tap water or sterile saline. The success rate of the pulpotomies after one year was 87.7 percent and after two years 80.4 percent (clinically and radiographically). This result was only influenced by the type of restoration (amalgam versus stainless steel crown). The results of the present investigation compare favorably with those of other published studies of pulpotomy of primary molars using calcium hydroxide as the wound dressing.
在这项随访研究中，一种光固化玻璃离子衬层粘固剂被评估为在第一恒磨牙的氢氧化钙活髓切断术中作为窝洞封闭材料使用1年和2年后的效果。活髓切断术的敷料是纯氢氧化钙与自来水或无菌生理盐水的悬浮液。活髓切断术1年后的成功率为87.7%，2年后为80.4%（临床和影像学评估）。这一结果仅受修复类型（银汞合金与不锈钢冠）的影响。本研究结果与其他已发表的使用氢氧化钙作为伤口敷料的第一恒磨牙活髓切断术研究结果相比具有优势。
